Glock Front Sight Install? LocTite 609?

[trackaddict88]

Just got my new Meprolight night sights. Rear sight install piece of cake. Front sight install-hmmm. The instructions say to use LocTite 609 which is neither red nor blue threadlocker according to Loctite's site but is "609 Retaining Compound General-Purpose" for locking Keys and Splines.

Can I use plain old red or blue? I don't see why not. Any reason why not? Anybody? Thanks, Steve.

Use Blue.

If you use Red, you will not get it apart again without twisting the little screw off.

Not that it matters.
You probably won't want it off again until the Tritium dies in about 12 years.

yep, use blue, it's for threaded applications. 609 is for slip or press fittings.
i use blue for all my gun applications.

good luck getting anything free when you use red, though you can heat it up to get it free.

plus another for the blue!

i don't think that i have ever used red?

#620 is sleeve retainer, don't use this, it is as unremoveable as red Loc-Tite, don't use the red stuff either for any gun application..
#609 is General Purpose locking compound, it can used to bathe dovetail blades on sights, keyways,etc. and as a threadlocker, you will need to bake the parts in a 350 F. oven to break the seal if you need to seperate the parts without damage.
#290 is the green threadlocker.
This stuff works like blue threadlocker but it can be tightened and loosened without having to reapply the solution to the threads.
Blue is best if you don't have the #290 threadlocker. HTH

I used blue for my front sight in both my glocks

Thanks all! I use and have plenty of red and blue in the garage but wasn't sure on the #609. It's done now.

All my Meprolight NS Came with the red loctite

Best wishes. I used blue on my front sight. Blew off the gun in less than 50 rounds. Use red.

Well that's real odd right there!
I have been using blue on Glock sights for about 15 years now.

The oldest Glock 23 still in my possession had the Meps installed in 1995, and they haven't fell off yet, although they are getting pretty dim!

Few things you need to do when using Locktight though.
#1 Degrease everything first so it's not slipping on oily threads.
#2 Use Locktight under the sight itself, as well as just on the threads.
#3 Let it cure for 24 hours before you go shooting.

If you follow those three rules, it won't ever fail.

BTW: You cannot use heat to remove Red or Blue Locktite on night sights. If you do, you will also destroy the epoxy encapsulated Tritium vials.

I used blue on my Aro-Tek front sight. After about 500 rounds I launched it off into the desert. The replacement sight has red locktite now. Mark

Red Loctite can be removed very easy with a little heat ..
